What value of c make polynamial below a prefect square ? x^2+10x+c
C=

the value of c is 25

Step-by-step explanation:

b/2a= 10/2(1)= 10/2= 5

(5)^2 = 25

x^2 + 10x + 25 = (x + 5)^2

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.
